Dem Primaries start

Iowa will vote for the very first Dem primary on Monday. As President Trump's acquittal is expected on Wednesday, is this the beginning of the end of the Dem primaries?

The negative campaigns against each other within the party is ugly inside out. The personal attacks leaking through the media and SNS have brought the political apathy and indifference. It is highly doubtful that anyone would sympathize with the accusation on the media attacks on their age, radicalism, or gender/race inequality.

Could Warren unite the party or is her medical plan extreme? Could Biden die during the possible Presidential term? Could Sanders pose serious challenges against Trump? Should the media not open the polls?
