It's looking more and more like Weld for 2020.
Gary Johnson will still be the ultimate, "Mr. Smith goes to Sante Fe," and then, "Mr. Smith goes to Washington." CNN and the RNC purposely leaving him out of the 2nd Republican debate in 2012 is why we have Trump -- Republicans were sick of the GOP establishment, and Johnson was a threat to that ... albeit far less wealthy (only about $30M).
I don't like Weld as much as Johnson, but Weld is more of your thoughtful, calm politician, whereas Johnson is the ultimate, self-deprecating fool we'd actually all love to have 'speak plainly' to us.
I just hope Weld would be as much of an a-hole to spending Congress as Johnson was. Johnson was the ultimate budget balancer, to an extreme, and the US really needs someone like him right now -- desperately.
Weld seems far more of a compromiser, and that bothers me. There is no more compromising on the budget, period, just like New Mexico when Johnson came to power.
