After months of warnings, the "Blue Wave" finally came to shore. Democrats took back control of the House, gaining 32 seats, a number that could increase to 38 or 39, depending on the results of the uncalled races. With the party back in charge of the lower chamber, much of the discussion around what their priorities should be has revolved around investigating the president and his myriad offinancial and political scandals. House Democrats have a clear mandate to fulfill their constitutional duty to provideoversight of the White House, but Democrats also have a mandate to address a number of major legislative issues. Though it's unlikely Democrats that will get any of these priorities pushed before the president and a Republican Senate, it's crucial that they signal to their voters what they want to done should they win the presidency and the Senate in the future.

Infrastructure

As a candidate and in the beginning of his presidency, Donald Trump promised to tackle the nation's crumbling infrastructure. That, of course, has gone nowhere and every "Infrastructure Week" ended in some scandal, quickly becoming anongoing joke. But thestate of America's infrastructure is nothing to joke about. Infrastructure spending has long been a Democratic Party priority before Trump attempted to co-opt it. Democrats should push that issue once again, proposing a bold infrastructure plan to repair crumbling roads and bridges, modernize public transportation systems, expand access to high-speed, fiber-optic Internet, and invest in green energy projects like wind, solar, and hydroelectric power.

Such an infrastructure plan would signal the party's commitment to investing in neglected communities and funding renewable energy projects such as a broader plan to combat climate change—not to mention open the door to the manyeconomic benefits of infrastructure spending. It would also establish a clear contrast with Trump's previous infrastructure plan that's been criticized as agiveaway to private contractors. The president has said he is willing to work with Democrats, so why not press him to keep his word? Democrats would be wise to pressure the president and his Republican supporters to prioritize infrastructure, or face political consequences.

Healthcare

No other issue played a bigger role in the Democrats' midterm success than healthcare. Their electoral message on healthcare was simple: Protect people with pre-existing conditions, expand coverage and stop proposed cuts to Medicare and Medicaid. Now they must deliver on these promises. House Democrats can immediately pass legislation to protect coverage for people with pre-existing conditions, pressuring Trump and other Republicans who have vowed to do the same to keep their word. With a full repeal of the Affordable Care act now temporarily off the table, Democrats should push to expand coverage and address the limitations of the ACA. These can range from introducing incremental policies that get support from more moderate Democrats, like legislation tostabilize insurance markets, to bolder policies that attract the progressive wing of the party, like allowing Medicare more power tonegotiate drug prices and proposing aMedicare buy-in for 55 to 64-year-olds.

While the long-term goal for the party should be to push for a Medicare for All system, these are positive steps toward a goal that still has a lot of opposition from within the party. Finally, any budget proposed by House Democrats should reverse any funding cuts to Medicare and Medicaid. Democrats have an ideal opportunity to push for a positive vision on healthcare and continue to have the upper hand on the issue heading into 2020.

Immigration

Bitter political battles over immigration, especially over funding for the border wall and the fate of DACA, will be a prominent feature of politics the next two years. Democrats are right to be alarmed over the administration's immigration policies like family separation and ending DACA, but now it's crucial they advocate for an immigration agenda in contrast to the Republican agenda. With the fate of DACA likely in thehands of the Supreme Court, Democrats must push for a long-term legislative solution. The most stable solution is the passage of the Dream Act. It would also be politically beneficial for the Democrats to bring it to the floor cleanly, without a compromise on funding for the wall. Furthermore, Democrats should schedule hearings about the family separation policy and Trump's pre-election decision to bring troops to the southern border in response to the migrant caravan. Democratic voters havebecome more liberal on immigration, and it's important the party signal to its base that they are willing to find solutions on the issue without compromising its core values.

Voting Rights

Much of the post-election analysis has focused on the effects of voter suppression, notably in Georgia, North Dakota, and Florida. These voter suppression efforts have only increased since theSupreme Court struck down the section of the Voting Rights Act, which required states with a history of racial discrimination to get permission from the Department of Justice when enacting any changes in voting laws. In response, states around the country immediately passed strict voter ID laws. Fortunately, the Supreme Court decision left the door open for future legislative action. House Democrats can immediately take action andstrengthen the Voting Rights Act. They would also be wise to propose legislation to make Election Day a federal holiday, or move Election Day to a Sunday, as it is in most places around the world. While Republicans are busy spreadingconspiracy theories about voter fraud, Democrats should take the opposite path and make it clear they will fight continuing discrimination in voting. For strategic and moral purposes, the party has an obligation to extend democracy in every way when voting rights are under tremendous pressure.
