And the highest number in a decade feels the country is less safe than it was before 9/11, according to a Fox News poll released Wednesday. The poll also finds most voters think President Obama has not been tough enough on Russia, although a majority still says the U.S. should stay out of the situation in Ukraine. Some 52 percent of voters think the country is weaker and less powerful today than it was six years ago.  That’s three times the 17 percent who say the country is stronger and more powerful.  About 3 in 10 think it is unchanged (29 percent).  Last year, 48 percent said weaker, 24 percent stronger and 27 percent unchanged (Feb. 2013). The number of Democrats saying the country is stronger now has dropped 11 percentage points:  it’s 32 percent today, down from 43 percent in 2013.  Twenty-two percent of Democrats say the country is weaker and 44 percent say it is the same.  More
