Basically its pointless to not invite in foreigners because they might vote Democrat. The Democrats will always divide people into groups.. and promise some groups tons of free things.
We can't beat them at that, even as some Republican politicians try.
We need to keep getting out the word of conservative freedom vs Democrat entrapment.
My wife is an Immigrant from China and a devout Republican. Has to do with being anti-communist. Basically Republican outreach can get to many more people like her if we invest in the time to let them know where we stand. Problem is we let the Dems do this for decades and now Rove and Melman caught on and are doing their best to recruit minorities. Looks like it is working.
