I leave it to others to judge if Walker can be trusted to abandon his past position entirely and execute his current immigration plan with resolute conviction and zeal if he is elected.
One thing is certain, Jeb Bush and Marco Rubio are utterly untrustworthy on this critical issue that poses an existential threat to the security, economic well being, and culture of the USA.
Walker is favored and supported by the Koch bros and they are proponents of immigration of any sort.
Walker, being of a northern state, has absolutely no idea what the illegal aliens are doing to this country. He needs to come on down to Texas and I can show him what it looks like. Purple and yellow house trailers with blankets for doors and 3 families living in it. Uninsured drivers with no license. No speaka ainglish. Welfare kings and queens working off the record for cash that gets sent back to Mexico. The hospital waiting rooms packed with whole families, hours to wait if you really need attention.
