but they don’t. Not the Des Moines Register endorsement of Romney, or the SLC Tribune’s endorsement of Obama, or Colin Powell’s endorsement of Obama, or Lindsay Lohan’s endorsement of Romney.
Sorry if the political science doesn’t correspond with your political sensibilities, but the only meaningful question about endorsements is: did an endorsement induce someone to vote for a candidate who was not already planning/leaning towards voting for that candidate?
And the answer, researched time and again by many people, is: no.
Which is absolutely the last thing I’m going to say about endorsements for quite a while.
