Today, voters in 10 states will head to their polling places to determine the allocation of 419 delegates to the remaining four GOP candidates. Last week, Gallup released the results of a new nationwide poll that found economic and unemployment issues to be the chief concerns of most voters. Healthcare and national security ranked not far behind while social issues and immigration trailed the pack.

In the graphic below, we provided a state-by-state comparison of search trends for the candidates and issue-related keywords for the past three days. While the economy and healthcare remained paramount across all Super Tuesday states, social issues like abortion and gay marriage ranked as the third most-searched terms in seven of them. Terrorism and national security ranked third only in Alaska, North Dakota, and Vermont. Among the candidates, Mitt Romney leads in searches for six of them, with Rick Santorum and Ron Paul split the rest. Ohio, the most closely-watched Super Tuesday state, is among those with Romney in the lead.
