Last week, some of you thought I was nuts to suggest that Hillary Clinton might be considering another grab at the brass ring. Don't be so quick to rule it out.

My theory is that the 13-city Bill and Hillary speaking tour to be launched in Vegas right after the midterms is a soft opening to Clinton 2020. Bill Clinton, one of the most astute observers of the political process, understands that the Democrats are offering only weak opposition to President Donald Trump's re-election. A crowded field of not-so-exciting candidates could propel Hillary to the nomination.

Some Democrats might actually rather take their chances with a Trump-Clinton rematch than watch a lesser candidate drive the party further into obscurity.

Several national Democrat strategists now see it the same way. Strategist Steve McMahon said on MSNBC's Hardball this week, "Some people close to the Clintons and close to Hillary Clinton who look at the field and think if Joe Biden doesn't run, it's an awfully weak field and someone like Hillary Clinton could get back in."

He is right.

Though he leads most hypothetical polls right now, I for one don't see Biden getting into the race. Biden is all bluster but has no stomach for it. He has run twice before and never really excited the masses.

The Clintons believe the nomination is obtainable and are giving serious consideration to a third run. Can you think of any circumstances by which you would welcome a Hillary Clinton candidacy, and would vote for Hillary for president in 2020?
