Why does every Democrat cheer the polls 20 months before the election that are showing Hillary ahead by 10-16 points?
Dude, it's because she is all the Democrats have left.
The entire country is pretty much Republican. The most watched news network is Fox. The most listened to talk radio show is Rush Limbaugh. There are 50 Governors, only 18 of them are Democrats. The Republicans just gained more seats in the House and Senate than they have had in decades. They have a huge white voter problem, so they try and spin that Hillary will win white guys in Arkansas.
It's all a pipe dream. I honestly think the Obama coalition is running the risk of becoming the rainbow coalition. If you like that, ask President Mondale and President Dukakis how well they enjoyed it.
It was a 52-48 split in favor of the Democrats in 2008 and 2012 (Democrats got a majority of the vote in House seats in 2012, but GOP-majorities had successfully gerrymandered most Congressional districts to favor the GOP) and about a 52-48 Republican split in 2010 and 2014. A 52-48 split hardly indicates electoral dominance unless something is screwy. The Republicans basically found ways to set up a few D-dominant districts in which the Democrat is likely to win 70-30 and dilute the rest of the Democratic vote in districts that go 54-46 Republican.
FoX News Channel may be the most watched cable "news" network, but it is also the most reviled. Rush Limbaugh is a sick joke except among right-wingers. If liberals get stuck listening to him they ask to change the channel. If nobody changes the channel they do so themselves. That's draft-dodging militarist Rush Limbaugh who bullied a maid into getting street oxycontin for him.
Republican elected officials may be the majority -- but their approval ratings are abysmal. As a nation we have had a hard time, and we are fussy. Some well-heeled plutocrats found a way of exploiting that discontent while saddling America with pols likely to do nothing but enrich those well-heeled heels. The ideal American to them is someone who asks for a pay cut and is so thankful for getting to keep his job.
Most of the potential Republican nominees for President have huge gaping holes in their personalities or stand for extreme positions.
I look at the map of GOP support and I see more connections to 'whiteness', religious affiliation (especially Mormons and Southern Baptists) or to thin population.
For political careers the best prediction on long careers is "perform or perish". Performance can be as simple as getting appropriations for job-creating public works. For most Republicans the key to success in getting campaign funds is to obey the Koch syndicate. "My" representative is a case in point; he gets lavish support from interests intent upon bleeding the the American middle class for a few plutocrats for whom we are told to suffer with a smile.
I wipe my hands on my shirt or my slacks rather than dirty them on Koch paper products.
