"Without borders, there is no country." 
Exactly. 
"Palin speaks for a lot of vocal Republicans who want the House GOP to
 take action, as well as speaking for even more Republicans who secretly
 agree with her. Her public advocacy for impeachment may rouse other 
prominent Republicans to join her, although it is doubtful many of them 
will be current office holders."
"But if things get much worse at the border, or if other examples of 
presidential overreach emerge, the cumulative effect of these 
transgressions could result in steps being taken in the House of 
Representatives to remove the president."
