"Are" trends

When searching the internet, when you type in a word Google will try and finish with the most sought after searches. This can give you an idea what other people around the world or country may be asking or writing about.
Example. “are democrats"
Results.
Are democrats blue or red
Are democrats liberals
Are democrats smarter than republicans
Are democrats elephants

Example. “are republicans"
Results.
Are republicans red or blue
Are republicans racist
Are republicans pro life
Are republicans stupid

Which brings up the question, are people making up their own minds or trying to follow a trend created by the bloggers.
I just found it interesting.
