The more they see, the less voters like

National Journal finds an inverse relationship between time spent in early Trumparty states and results in the polls:

Between Me­mori­al Day and Labor Day, Bobby Jin­dal and Rick San­tor­um were the most fre­quent vis­it­ors by far to Iowa, ac­cord­ing to data com­piled in Na­tion­al Journ­al‘s Travel Track­er. Jin­dal logged 33 days in the state, which ac­coun­ted for two-thirds of his total cam­paign travel that peri­od, com­pared to 25 days for San­tor­um, who re­cently com­pleted a tour of all of the state’s 99 counties. However, both can­did­ates re­main stuck in the low single-di­gits in sur­veys of Iowa Re­pub­lic­ans, and are once again on track to be re­leg­ated to the second-tier GOP de­bate next week.
