@revelette2,
I think the WH is extremely important. Consider what Obama has achieved versus what Bush 2 "achieved". Or Johnson versus Nixon. And then there's the aspect of the Supreme Court and that has profound consequences that can last a generation. But yes, we definitely want a Senate which is not held by a group who believe their tenure there has two functions: 1) gaining/retaining power regardless of all else and 2) obstructing governance rather than facilitating it.
Dems consistently gain the popular vote in presidential elections for the reason that the majority of Americans prefer their candidates over the GOP candidates. And there is consistent polling that tells us Republican voters are more closely aligned with many Dem policy prescriptions than they are with modern GOP policy prescriptions which is why people like Ryan hardly ever get around to actually being specific on matters like budget or Obamacare replacement. When Bush openly pushed for SS "reform", even his base went for his throat. And for good reason.
I'm not worried about Trump taking the White House. He's surprised everyone so far, no question, but that was in relation to the right wing activist base and their racism, xenophobia, and misogyny was broadly underestimated. As was their trained-in hatred of government (a near half century project - you can carbon-date it to the Powell memo - very smartly executed).
