The OP just might refer to a former First Lady.

Democrats go their own way on that.. Republicans not so much... and who they have in their lineup right now is pretty sad

Though I think Rick Santorum would have an argument that it's his turn since he held out the longest against Romney

Jeb has a lot of establishment support but he's not the "it's his turn" candidate.

My guess is that either Santorum or Ryan would be an easier opponent for the Democrat to defeat. Jeb has the handicap of the Bush name but otherwise is generally perceived as more moderate and sensible than either of those two.

is often divorced from reality.

I seem to remember that too. I thought it was stupid language.

We haven't had one in a HELL of a long time!

which political party holds office regularly.

If it's in relationship to Hillary Clinton - I think the argument is more that she has experience and has served the Democratic party loyally for years, and the party should reward her loyalty and service, and recognize her experience by giving her the chance to run. That's not an argument I buy (because I think we should have a more liberal candidate), but it's understandable.

If it's in relation to changing parties - it's pretty goofy, like the argument for divided government. It might well make sense for a party who favors change in one house and a party who wants to limit change in the other, but the Republicans these days are so far round the bend, I can't understand thinking that you can have any balance with them.

As far as the next Democratic presidential candidate goes, I'm backing whoever gives us the maximum opportunity to keep the White House out of Republican hands. I may not like all of Ms. Clinton's political viewpoints, but the possibility of all three branches of the federal government being under radical conservative control---and let's not kid ourselves, that's where things stand---is completely unacceptable. For the time being, I'm putting my ideological wish list aside as an impractical luxury, and once she makes her candidacy official, I'm supporting Hillary.

And Jeb is probably thinking it, although is likely clever enough not to say it out loud...

and will make a great president.

Unfortunately they make up the majority of voters.

They fall for mindless slogans like that one, like "he was for it before he was against it", "they hate our freedom" and countless others.
