Wood chips come from the interior of a tree. This mulch is available as hardwood or softwood, or as a mixture. Hardwood mulches, according to Fine Gardening, will last a little longer than softwood mulches. Wood chips, in general, do not last as long in the landscape as bark mulches.
There have been more Republican presidents than Democratic presidents. Between 1789 and 2013, 43 people have been sworn into office as the president of the United States of America. Of these, a larger number have belonged to the Republican Party than have belonged to the Democratic Party.
This would technically make it 18 Republicans to 14 Democrats. Since the first presidency in 1789, and until 2013, there have been 44 total presidencies in the United States. This includes only those presidents who were sworn into office, not acting presidents. Of course, not all of those who held office have been Democrats or Republicans.
