Long way to go before 2018 midterms. If Congress passes tax reform and repeal of most of Obamacare, the polls will change. The state of the economy, the results of the Russia investigation by the special counsel, the impact of the latest revelations on Uranium One, the Steele dossier, the Clinton Foundation, etc. will influence the polls. And then are foreign policy issues like North Korea, Iran, ISIS, Syria, and Russia that could dominate the news.
Add to this the current reality on how many Congressional districts are really in play. The Reps have a decided advantage thanks to gerrymandering. In the Senate the Reps have 10 seats up in 2018 compared to over 20 for the Dems.
The Dems will have the advantage of more energized voters. Turnout will be key. Trump will be urging his voters to give him the people he needs to drain the swamp. Historically, the Dems will make gains in the midterms following a Presidential election. The question is how many.
The poll is pretty much accurate. It doesn’t take into account that us Conservatives hung up on them or said we wouldn’t vote for the republican candidate if he/she wasn’t a conservative.
