Based on election trends over the last eight years, that seems unlikely. Current riots, violence, and other Democratic tantrums are unlikely to impress voters, either. You need effective policies, not just hate.
And you need effective candidates. With the collapse of the Democratic farm team, all you have is septegenarians like Elizabeth Warren and Bernie Sanders.
Democrats have no bench, and few positions for candidates to gain the necessary experience. That is what happens when you are rejected by voters and have nothing of worth to offer.
Last eight years.. what an incredibly arbitrary timeframe to examine.
Actually, it's a very pertinent time frame. Eight years ago, Democrats controlled the White House, the Senate, and the House. It is the 8 year period after Obama was elected that Democrats lost the White House, lost the Senate, lost the House, lost most governors offices, and lost over 1000 seats in state legislatures when voters abandoned the Democratic party.
Obama very nearly destroyed the Democratic party single handed.
