Because the field is so large right now, each Independent, Tea Party, GOP candidate must start to distinguish themselves from the rest of the field. Pawlenty will use economics as a strength.
Much of the responsibility of the candidates choices and strategy of the election means that independent, GOP, and Tea Party must work together to field the candidates with the most chance of fulfilling common conservative values and winning the election. If the candidates are not real conservatives, they will lose the election. The majority of the American voters want real conservatives representing them in Washington D.C.
