The Iowa caucuses are going to give one Democratic presidential hopeful a boost as the primary season kicks off on Feb. 3. Which candidate? That will most likely depend greatly on what the caucus electorate looks like on that day. And in recent election years, that has varied a lot.
The caucuses always arrive as something of an unknown and they can be predictive, not just on who the nominee will be but who this cycle’s Democratic voters are. How tuned-in are voters this cycle? Is there one group that seems especially engaged? CONT.
