Considering her schedule, I would say Coulter is relevant and a conservative voice. SHe routinely makes appearances on multiple media outlets. She is still publishing. If no one were buying her books, she would not get published.
And she is absolutely right about one thing, if Trump abandons his efforts to get the wall, then he will not get a second term. That was his marque issue, to end the endless flood of illegal invading aliens into our country, to reduce the illicit drugs that are killing 70,000 of our people each year, and to reduce the human trafficking over the border which is pervasive.
The Dems only care about the illegal invading aliens, many of whom are criminals that are murdering and raping enough Americans to warrant building that wall high and strong.
Anyone voting for a Democommie is suffering from a mental illness.
