BOSTON (AP) — The cash is flowing in Pennsylvania's hotly contested campaigns for an unprecedented three open seats on the state Supreme Court, as contributions to the dozen candidates surpassed the $5 million mark and TV advertising intensified heading into Tuesday's primary election. Nearly half of the money has been spent on air time as the would-be nominees work to bolster their name recognition and prepare to take their chances in statewide balloting that is limited to the state's roughly 7 million registered Democrats and Republicans. The Supreme Court campaign is likely to set a state record for judicial campaign spending. Since the final pre-primary campaign finance reports were filed May 8, the candidates have been required to report contributions of $500 or more to the state within 24 hours.
