Tom Tancredo is best known (where he is known) for his position on immigration. That led me to expect very little from him as a candidate. I was pleasantly surprised to find a candidate who seems to have a very down-to-earth perspective. From my perspective he would be a capable president who would tackle the issues in a straightforward manner. I would expect him to work with others while standing for his principles.
I am happy to endorse Tom Tancredo for President.
UPDATE 5/21/2007: Based on further information resulting from comments below, I have concluded that I cannot endorse Tom Tancredo. I am not convinced that he is committed to many of the positions that he claims to hold – with the exception of his position on immigration. I fear that he is doing nothing more in this presidential run than muddying the waters of the Republican primary.
