The bus tour could also be simply a preface to Palin's next reality show, talk show, book or other product. Some candidates write books to help raise their profiles as candidates; some entertainers take up issues or causes to make themselves be seen as more serious, but Palin just keeps talking and drawing attention to herself as both an entertainer and a politician, like some weird far right Energizer Bunny that never stops, but always keeps her options open.
Fighting jihadist terror and being at war with Islam are, of course, two different things that can remain distinct from each other. The Bush and Obama administrations both went to great efforts to try to make it possible to maintain this distinction. Nonetheless, official statements that the US is not fighting against all of Islam and even the reality that Muslims enjoy more religious freedom in the US than in almost any other country in the world, something which both Presidents Bush and Obama have pointed out while in office, will be very easily overshadowed if this Islamic Center is not allowed to be built now. It has become almost a cliché to point out that the current Republican Party would have rejected Dwight Eisenhower or Ronald Reagan for being too liberal, but the debate over the Islamic Center suggests that they would reject George W. Bush on these grounds as well.
