The problem is big cities are expensive to advertise in, thus tilting the race against dark horse and insurgent candidates.
Does anyone else feel that the current system of primaries/caucuses forces candidates to cater their messages towards the interests of rural/small town/and suburban voters. IA and NH largely decide the fates of candidates as well as SC. NV has Las Vegas but that's not like a real big city. I wish Illinois, NY, CA, TX, or PA could be chosen as an early primary state especially, perhaps NY.
No thanks, the big cities have enough power as is. Besides, your system would guarantee a Clinton/Giuliani style election every time.
Isn't southern New Hampshire fairly close to Boston, anyway?
