perhaps your point is more accurate.
if so, it seems a bit sad she has to do this.
I remember when Bob Dole resigned from the Senate to “concentrate” on his presidential bid against Hitlery’s “husband” in ‘96. Didn’t do much.
Of course, Marine is in it to win it...Bob was there because it was his turn. :)
