I can't answer that because I'm not a Republican, but they probably vote along party lines like the Demos do and get the same results like Dems voting in Detroit, Chicago, DC, LA, or Cleveland .
the real simple answer is: you haven't done your home work....all the major economic disasters from the beginning of the 20th century until present day have been caused by progressive Democrats.....
the apart from obama who will claim the title....the two worst presidents in US history....wilson & FDR.....
to make your education simple....rather than argue with you....go to wikipedia (for quick reference)....
search two things....actually three....
1) the list of presidents
2) the US depressions and recessions
3) US foreign wars
overlay the economic disasters and wars over the presidential terms....
you'll be amazed....9 of 12 wars caused by DEMOCRATS
two worst depressions/recessions caused by DEMOCRATS (progressives)
